The location of Washington Square once was the site of Corbett's Thatched Tavern. The city square was opened in 1818.[4][5]

Along the east wall of the park is a monument to Gen. Pierre Beauregard, the Confederate general in charge of the city's defenses in 1862-1864. In 2004, the monument had repair work performed to correct a lean that had developed.[6]

In the center of the park is a memorial to the Washington Light Infantry. The memorial is made of Carolina gray granite and is a miniature version of the Washington Monument in Washington, D.C. The memorial is about forty-two feet high and is inscribed with the names of important military battles. It was unveiled on February 23, 1891.[8][9]

A statue of William Pitt the Elder was once located in Washington Park. The statue suffered repeated damage, including a decapitation from a falling tree branch in November 1938, before being moved to the County Courthouse.[10] A statue of George Washington was later installed on the base of the Pitt statue following some local controversy. Plans for the new work began in 1992. The Washington statue was going to be a twice-life-size sculpture by Felix de Weldon.[11] Eventually, Jon Michel was chosen instead. The work, which cost $165,000, was unveiled on December 14, 1999.[12]
